NEW QUESTION # 103
An administrator wants to implement a virtual switching technology that implements a single control-plane solution. Which S-CX switches would meet these criteria?
- A. AOS-CX 6300, 6400, and 83xx switches
- B. AOS-CX 6300 and 6400 switches
- C. AOS-CX 6300 switches
- D. All AOS-CX switching platforms
Answer: A
NEW QUESTION # 104
Examine the AOS-CS switch output:
Based on this output, what is correct?
- A. 802.1X authentication occurred and downloadable user roles are deployed
- B. A local user role was deployed using a ClearPass solution
- C. 802.1X authentication was successful, but MAC authentication is yet to start
- D. Only 802.1X authentication is configured on the port
Answer: A
Explanation:
The role 'aruba_contractor-3044-7' is the exact correct format for a DUR.
NEW QUESTION # 105
An administrator wants to drop traffic from VLAN 6 (10.1.6.0/24) to VLAN 5 (10.1.5.0/24), but allow all other traffic. What is correct configuration to accomplish this?
- A.
- B.
- C.
- D.
Answer: B
NEW QUESTION # 106
Which HPE Aruba Networking ClearPass configuration is required to implement DUR?
- A. Create an admin user role
- B. Configure an HTTPS certificate
- C. Import RADIUS dictionary attributes
- D. Enable the RadSec service
Answer: B
Explanation:
To implement Dynamic User Roles (DUR) with Aruba ClearPass, an HTTPS certificate must be configured.
This certificate enables secure communication between ClearPass and the Aruba CX switches for role downloading and authentication.
RadSec service enables secure RADIUS but is unrelated to DUR certificates.
Admin user roles and RADIUS dictionary attributes are necessary but secondary to certificate requirements.

What is correct about access from the servers to the Core?
- A. Server 1 and Server 2 can communicate with each other via the core layer.
- B. Server 2 can successfully access the core layer via the keepalive link.
- C. Server 2 cannot access the core layer.
- D. Server 1 can access the core layer via both uplinks.
Answer: D

NEW QUESTION # 110
While troubleshooting a scenario in which the customer has added two new line cards on an HPE Aruba Networking CX 6400 switch, the LEDs on the line card do not show light on the first card.
Which troubleshooting methodology should you use to isolate the problem?
- A. Divide and conquer by swapping the line cards in their slot.
- B. Spot the difference by comparing the switch configurations.
- C. Follow the path and check the connectivity from the access switch to the CX 6400.
- D. Replace the configuration using the previous checkpoint on the switch.
Answer: A
Explanation:
When line card LEDs do not light up, and the cards are newly installed, the best troubleshooting methodology is Divide and conquer by swapping the line cards. This method isolates the problem by testing hardware in different slots or known working units.
Spot the difference involves comparing configurations, which does not directly isolate hardware failure.
Follow the path is more suited for connectivity issues.
Replace configuration relates to software or config problems.
Hardware issues are best isolated by physically swapping components.

NEW QUESTION # 111
You are remotely connected to an HPE Aruba Networking CX 6200F switch using SSH to change the Control Plane ACL, allowing only defined subnets to access the switch. Which AOS-CX command allows you to roll back your change if the ACL change is wrongly formed and you can no longer log in to the switch?
- A. Use the checkpoint auto command after you commit the change.
- B. Use the checkpoint auto command before you commit the change.
- C. Use the checkpoint commit command before you commit the change.
- D. Use the checkpoint commit command after you commit the change.
Answer: B
Explanation:
When making changes remotely to critical configurations such as Control Plane ACLs on a CX switch, to protect against accidental lockout due to misconfiguration, you should enable checkpoint auto before committing the changes.
Checkpoint auto creates an automatic rollback timer. If the administrator loses connectivity (e.g., because of the ACL change), the system automatically rolls back the change after the timer expires, preventing lockout.
checkpoint commit is used after committing to save the checkpoint explicitly, but it does not provide automatic rollback.
Running checkpoint auto before committing is essential to have the rollback safety net.

NEW QUESTION # 112
You have run a script to configure a new VLAN on a CX switch, but are receiving a '404 - Not Found' HTTP response code.
What do you need to do to resolve the issue?
- A. Correct syntax error contained in the data payload.
- B. Send a POST request to the /rest/v1/login resource.
- C. Enable the switch REST API in read/write mode.
- D. Specify the /rest/v1/system/vlan URI in the request.
Answer: D
Explanation:
When receiving a '404 - Not Found' HTTP response while attempting to configure a VLAN via REST API, the most common cause is specifying an incorrect URI endpoint. The correct approach is to specify the exact resource path for VLAN configuration, which is /rest/v1/system/vlan. Without the correct URI, the API will return a 404 error indicating the resource is not found.
Sending a POST request to login is necessary but not related to 404 after login.
Syntax errors in payload lead to 400-series errors but usually not 404.
Enabling REST API read/write is important but would result in different errors.

NEW QUESTION # 113
You are implementing a design where the campus network should be in an isolated spanning tree topology from the data centre network. The core switches are connected by a single Layer-2 interface carrying multiple VLANs.
When you examine the switches, you discover that the campus core sees the data centre core as the root bridge.
What configuration can you apply to the campus-to-data centre core link to resolve the issue?
- A. BPDU guard
- B. BPDU filter
- C. Root guard
- D. Admin edge
Answer: C
Explanation:
To prevent the campus core from seeing the data center core as the root bridge in a spanning tree topology (which can cause suboptimal paths or loops), Root Guard should be applied on the campus-to-data center core link. Root Guard enforces root bridge placement by blocking any superior BPDU from a downstream switch, maintaining the intended root bridge location.
BPDU filter blocks BPDUs entirely, which can cause problems.
Admin edge and BPDU guard are related to edge port protection, not root placement control.

NEW QUESTION # 114
Examine the following AOS-CX switch configuration:
Which access control entries would allow web traffic to the web servers 10.1.0.100 and
10.1.1.100?
- A. permit tcp any 10.1.0.100/255.255.254.255 eq 80
- B. permit tcp servers eq 80
- C. permit tcp any 10.1.0.100 0.0.1.0 eq 80
- D. permit tcp any 10.1.0.100/10.1.1.100 eq 80
Answer: C
NEW QUESTION # 115
Which statement is valid when enabling ARP protection features on HPE Aruba Networking CX switches?
- A. Once you enable DHCP snooping, you can enable ARP protection, and you will have full information to mitigate security risks.
- B. DHCP server utilization is required for IP to MAC binding to enable ARP protection.
- C. Client lease time on the DHCP server should be at least 3600s before enabling ARP protection.
- D. In an active network, you should generally wait at least a week after enabling DHCP snooping to enable ARP protection.
Answer: D
Explanation:
When enabling ARP protection, it is best practice to wait at least a week after enabling DHCP snooping before enabling ARP protection in a live network. This allows the DHCP snooping binding table to stabilize, ensuring ARP protection has accurate IP-MAC bindings, reducing false positives.
Immediate ARP protection may cause legitimate traffic to be dropped.
Lease times and DHCP server utilization are less critical.
This staged approach minimizes disruption.
